Repository sharing code and the model for the paper "Rescoring Sequence-to-Sequence Models for Text Line Recognition with CTC-Prefixes"

Overview

Rescoring Sequence-to-Sequence Models for Text Line Recognition with CTC-Prefixes

Setup

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

Run on IAM

source venv/bin/activate
python run_iam.py --model=model/best_lm=0.5_beams=5/serve --data=data/test.lst

Shared Code

In src we share our implementations of the beam-search and the CTC-prefix-scores. Note, that the full algorithm is build in the Tensorflow graph which is why a simple model.predict is sufficient to obtain the decoded sequence.
